RCBS Precisioneered Dies are for shooters who demand reloads equal to the quality of their guns.

2-Die Sets are for bottleneck type rifle and handgun cases, and consist of a full length sizer die with expander-decapping unit, and a seater die with bullet seater plug.

Full Length Sizer dies for bottleneck cases have vents to prevent case damage from trapped air or excessive lube. Each die is properly hardened and hand pollished. Seater dies have built in crimper appropriate for the particular caliber. Bullets can be seated without crimping.
Standard 7/8 x 14 thread size.
